Letters Patent No. 106,299, dated August 9, 1870.

IMPROVEMENT IN STOIEIPINGv MEHANISM EUR, SPINNING- AND OTHER MACHINES.

The Schedule referred. to in these Letters Patentla'nd making part ofthe same.

To all whom it ana-y concern:

Be it known that I, SAMUEL 4B. WEsTooTT, of River Point, in the countyof Kent and State of 1l Improve- Rhode Island, have invented new andusefi es for Spinningments in Speeders Vand other Machin and TwistingCotton, Sto.; and do hereby decl-.tre the following to be a-full andcorrect description thereof, reference being had. to the accompanyingdrawing making part ot' this specification, and to the letters andnumbers of reference marked there-ou, similar letters and numbers beingused in all the figures to denote the same part.

In tlnx drawing- 1 Figure l is a back elevation of a speedcrframe,showing only so much of the machine as is necessary to explain theimprovements.

Figure 2 is a top view of the saine. Figure 3 is a verticalcross-section, taken just in' Figure 4 is a view of wheel F, seenedgewise.

B is the frame of the Speeder.

S is the hack roll, running inthe usual bearings.

A gear-wheel, o, on the end of the roll, meshes into and drives agear-wheel, o', on a stud below.

D is a rocker-shaft,carrying the vibrating bar y.

AA is an inclined cover -placed over the rocker- 'shaftt cis aguide-tube fastened to the upper end of a bar, q, which passes downthrough an opening in the cover A, the har being hung on a pivot at thatpoint, lso as to allow it to fall back toward the cover Awhen the sliverbreaks, `the lower 4part of this har. being bent at au angle ofabout-'forty-ve degrees to the upper. i y

N is .a table orrest, supported fby arms projecting from the cover A,and having un opening in it, (see iig. 3,) through which the roving oryarn z passes to thef-tube c.l`

j is an arm fitted to swing on a stud in the face of gear-wheel o'.

It has a slot iu its lower half, through which a pin ln the end of arm tworks, and there is alsoa sliding plate, n, fit-ted into the back of thearm j, the lower end of which is also htted onto the nin in the end ofthe arm i.

The upper end of the plate n is drawn back of the C is a `shaft drivenby thev gear-wheels a anda', the last-named gear being fast on the backroll S.

F is a pulleyapplied to a stud fast to the frame, and having tworecesses in its edge, in which the shaft G will turn without revolvingthe pulley, but the shaft C is placed close enough to be in contact withthe other parts of the periphery ,of the pulley, and to turn it at timesby `ii-iction.

V is an arm projecting out from the shaft H, and

catch'ingon a pin, b, in the side of the'pulley F, to prevent it fromturning, and a spring, f, presses on the other pin b, to turn the pulley'when the arm Y is moved away from the pin b.

XX are two inclined planes on the hack of the pulley F, which, when thepulley turns, press against the lever NV, and, through it,slide the rodg, which throws off vthe driving belt.

k is a sliding bar, guided and held by a pin in the end'of'the shaft D,which projects through a slot iu the bar, the other'end of the harheilig connected with the crank X on the upper end of the shaft H.

A spiral spring,p,on the lower end of the shaft turns it so as tomakearm V press against the side-gf the pulley F.

The guide-tube c has a longitudinal spiral slot in the top and side ofit, through which" the roving or yarn may be passed it through endwise.

The operation is as follows n The Speeder being put in motion, thegear-wheel 0 in the back roll turns the wheel o', which gives a rockingmotion to the shaft D by the barj and arm t, and this causes the plateyto vibrate in and out under the cover A.

So long as the rovingzcontinues whole it holds the to avoid the troubleof threading guide-tube c up level, and keeps the lower end of the bnrg, to which it is att-ached, up .out of the `way of the plate y. But,when the roving breaks or runs out,

the tube c will fall back, and the lower end of the bar g will drop downin the way of the plate y, and stop its vibrations. This will cause thebarj to slide down on the pin in the arm t, and throw out the 'upper endof the plate nagainst thev end of the har k, which pushes the shaft Haround so as to throw the arm V off from the pin b, when the spring f,pressing ou the other pin b, causes the pulley F to turn far enough toimpiuge against the shaft C, which gives it a half revolution, bringingone of the inclined planes X' against the lever W, which slides the barg and shifts the driving-belt, stopping the Speeder.

Having thus described m-y improvements,

IVbat I claim as my invention, and desire to secure by Letters Patent,is

' 1. The combination and arrangement of the pulley F with plus b b onone of its sides, and the inclined planes X X on the other side, withthe springs f, arms V und W, and shafts H and C, 'substantially as setforth, and for the purpose specified. 2. lhevslot-ted harj, with plate nand spring c, in combination with the bar k, arms t, 1, and q, andshafts I) and H, substantially' as specified, and furthe purpose setforth. 1 Witnesses: SAMUEL B. WESTCOTT.
